Best Petrol Lawn Mowers Buyers Guide

There are many different reasons why you may be considering purchasing a petrol lawnmower. One of the main reasons why people go for this option for their gardens or business is because they are not going to be tied to a power supply, which means that they have much greater flexibility. You won’t need to be restricted in terms of having to be near a power port in order to use your lawnmower. This also means that there is no risk of cutting through the cable with the lawnmower, which a lot of people have experienced when using an electric version. Aside from this, petrol lawnmowers make mowing the lawn much easier because they have a lot more power when compared with hand-driven or electric mowers. So, when you take all of this into consideration, it is not difficult to see why a petrol lawnmower is a purchase that makes sense. However, the only difficulty is that there are so many different petrol lawnmowers on the market today, and so this can make it feel impossible to narrow down your search effectively.

Lawn Mower Buyers Guide 

Now that you have an idea of some of the best petrol lawn mowers we recommend, let’s take a look at some of the different factors that need to be considered when making this sort of purchase. After all, you need to make sure that the petrol lawn mower you select is right for your needs and your garden.

When buying any sort of lawn mower, the first decision you need to make regards the power. Of course, in this buying guide, we are providing advice and suggestions pertaining to petrol lawn mowers specifically. However, if you want to know more about how petrol fares up with the likes of cordless and electric lawn mowers, we will provide these details in the next section. 

When purchasing a petrol lawn mower, one of the biggest decisions you are going to need to make is the amount of power that is required. Check out the engine power, which tends to be quoted in horsepower, which is bhp or hp. The higher the horsepower, the more powerful the engine is going to be. The ideal range for ample rotary power is between 4bhp and 5.5bhp. However, this does depend on a number of different factors, including how wide the lawn mower is. If you are looking for a cylinder lawn mower, you will be able to manage a little bit less power, for instance, you can start from around 3hp. More power is required for the wider lawn mowers, so do keep this in mind. 

Aside from this, you are going to need to consider what brand you are going to purchase your lawn mower from. There are a lot of different brands on the market today. This includes everything from Hyundai, which is our top pick, to Subaru and Kawasaki, amongst many others. 

The Internet has become a great source of information when it comes to buying different products today, and this is definitely the case when it comes to petrol lawn mowers. You are certainly advised to take the time to read reviews that have been left by people that are considering purchasing the lawn mower you have your sights set on. You will be able to get a general feeling of whether people are happy with this product or not. It is always important to use independent review websites so that you can be sure that the comments are 100% genuine. 

One thing to keep in mind is that there are a number of different types of lawn mowers. The three main types that you have at your disposal are hover petrol lawn mowers, petrol cylinder mowers, and rotary petrol lawnmowers. So, let’s take a look at each option in further detail to help you get a better understanding…


  • Rotary petrol lawn mower – This is the most popular type of petrol lawn mower out of all of those that are available today. There are a number of different reasons why this is the case. This includes the fact that they tend to be a lot cheaper when compared with other models that are available. This type of lawn mower will cut the grass with a blade that rotates rapidly, slashing it as you go across the grass. The blade spins parallel with the ground. This is an effective method for cutting the grass but it is not as fine as the cylinder cut, which is something we will discuss next. If you want to produce a striped finish with your rotary mower, you should be searching for a mower that comes with a rear roller. There are a number of other benefits that are worth considering when it comes to this type of lawn mower. This includes the fact that they are very effective when it comes to cutting longer grass. This is because of the motor, which is powerful due to the petrol engine combined with the cutting action. So, if you are often tackling long grass, this is definitely a type of lawn mower that would be worth considering. 
  • Cylinder petrol lawn mower – The next type of lawn mower that we are going to discuss is the petrol cylinder lawn mower. When compared with the lawn mower that we have just mentioned, these models are more expensive. However, a lot of people do believe that the added cost is justified. With this lawn mower, professional groundskeepers, landscaping business owners, and connoisseurs in the world of gardening tend to go down this route. This is because they offer the best finish due to the scissor-like action they provide. Combine this with the flexibility and range that you get from a petrol engine, and it is not hard to see why you have what many deem the perfect solution. When preparing cricket pitches and bowling greens, a petrol cylinder is always used, and so this gives you a good understanding of the sort of immaculate finish you are going to get if you opt for this type of product. However, as is the case with all products, there are some drawbacks that need to be considered. This includes the fact that this sort of machine is not ideal when it comes to handling longer grass. This is because they have a tendency to simply flatten the grass instead of cutting it.
  • Hover petrol lawn mower – The third and final lawn mower on the market today is the hover petrol lawn mower. This acts in the same way as the rotary mower in terms of the manner in which it functions, i.e. a horizontal blade that spins at a fast rate, cutting the grass as it goes. However, the difference is that there is a fan included in this lawn mower. It also has a skirt, which is designed to trap air and direct it in order to make the mower float. This makes this sort of lawn mower suitable when you are dealing with uneven surfaces, especially if there is some sort of banking. These lawn mowers will never hold you back, no matter what sort of direction you want to go in. You can expect the cut quality to be the same as the rotary petrol lawn mower. However, these models are often not as effective as the rotary version when it comes to long grass, as it can impact the airflow that is required to create the cushion to float the mower, and so you do need to have this in mind. Hover lawn mowers are usually of the electric kind, and so finding them in a petrol version means your options are going to be a bit more limited.


We have only just scratched the surface of the different factors you need to consider when you are looking for the best lawn mower for your needs. You need to think about the starting mechanisms used. There are a number of different options, including an electric start, recoil start, or electric key start. And, what about the fuel type? You have two-stroke and four-stroke engines. The vast majority on the market today are four-stroke. However, you do need to be mindful when purchasing. If you do happen to opt for a two-stroke, you will need to have special additives for the fuel.

Aside from the points that have already been discussed, the cutting width of the lawn mower is important. This will be based on the size of your garden, as well as storage requirements. You also need to consider the height of the cutting action when going for a hover version.

There are lots of different unique features and types of lawn mowers available to purchase. For example, some of the lawn mowers available today come with a blade brake clutch. This enables the engine to be left running while the blades are stopped from rotating. This is helpful if you tend to leave your mower in one place for a little while or if you need to cross paths while you are mowing. This will mean that you do not need to stop the engine and then start it again. In addition to this, you have self-propelled lawn mowers. This will direct some of the power from the engine to drive the wheels, which makes it a lot easier for you to push the lawn mower. You will still need to guide it, of course. However, this is a good option if you have a lawn mower that is heavy.

Petrol v’s electric v’s cordless lawnmowers 

You may be wondering why a petrol version makes sense over the different options that are available. With that in mind, we are going to provide some information on the differences between petrol, electric, and cordless lawnmowers so that you can get a better understanding.

Needless to say, there is no right or wrong answer when it comes to selecting a lawn mower in terms of the power options that are available. Some lawn mowers are going to be better suited than others, depending on your circumstances.

Naturally, you can expect more power with a petrol lawn mower. This makes this product the best choice for any garden that is more than 200 metres square. It also makes it ideal for situations whereby mowing the lawn can be challenging because of uneven surfaces or slopes. You should never skimp on power because it is one of the most critical factors for easier grass mowing and a good cut. 

With an electric lawn mower, power is just as important of a consideration when you are searching for the best lawn mower for your requirements. Nevertheless, it is important to point out that you are never going to be able to get as much power with an electric lawn mower as you would if you went down the petrol route. Despite this, there are people who prefer to have an electric lawn mower because this means that they are not going to need to service an engine. In addition to this, electric lawn mowers tend to be lighter than their petrol counterparts and you do not need to deal with any fumes coming out. However, having to use a lawn mower with a cable can be very frustrating and inconvenient, especially if you have a big garden or you are looking to purchase a lawn mower for your landscape or gardening business. In this case, you would be better off going for a battery i.e. cordless lawn mower, if you do not wish to purchase an electric one.

When it comes to electric lawn mowers, there are electric hover mowers that have internal grass compartments. While these products have become very popular, there are not recommended. This is because the moving height needs to be adjusted with a spanner, which is extremely inconvenient. Plus, when it comes to collecting the chippings, they are not very effective. Plus, the extra weight of the box filling up is going to lower the cut. So, as you can see, this sort of lawn mowers can come with all sorts of problems. While they may seem good on the surface, they do not really live up to the hype, and so it is vital to keep this in mind when you are searching for the best lawn mower for you. 

It is worth pointing out that you can get manual lawn mowers as well, although there are very few people that prefer this type of machine. These are basically small, cylinder type mowers. If you have a small lawn, which is even, then this would be appropriate. However. That’s about all they are good for, and very few people want to handle this task manually, which is why they are, understandably, not very popular! 


As you can see, there is a lot that needs to be considered when looking for a petrol lawn mower. Nevertheless, it is vital to make sure you take the time to consider your options carefully so that you end up with the perfect lawn mower for your needs. After all, everyone has different requirements when it comes to taking care of their garden. Perhaps you are looking for a lawn mower because you run a small business and need to use it for that? In that case, versatility and efficiency will be the name of the game. Carefully consider your requirements so that you can easily narrow down your search for the best petrol lawn mower for you. One thing is for certain, though; if you go for one of the options that we have suggested, you are not going to be disappointed!
